There was a popular song years ago that went " Who let the dogs out?" And that's a question that's apropos this week in the media. The answer is President Obama let the dogs out in his recent speech in Milwaukee. Alluding to his opponents he said, 'They're talking about me like a dog." What does this tell us? Language reflects thought. While some studies state that words are only 7 per cent of the message, words are powerful. They give us insight into what the speaker believes and feels. In this case, Obama is saying he feels like a victim. The key is the wording "They're talking about ME". It's something that is happening to him. It's not the language of leadership. There is a difference between being genuine and appearing weak.
Former Mayor Giuliani showed genuine sadness during the bombing of the World Trade Center but he never spoke like a victim.

The dog statement was not written in the speech. He acknowledged that he went off message. When giving a formal speech that's televised it's best to stick to the script especially if the speaker is in an emotional state. Otherwise, you might end up in the dog house.
